Event id 7031, you will have to wait until M$ provides a fix it happens during shutdown and its Sync Host session, I have the same.
Same for Event id 10010, Cortana, not much to do.
Now Event Id 10016 can be easily fixed. When you look @ the Event Viewer description there is a CLSID and an AppID involved.
You will have to open regedit with admin rights, navigate to HKeyClassesRoot\CLSId and when you find the id in question, right click then Permissions and temporarily change owner from TrustedInstaller to Administrators.
Same for HKEYLocalMachine\Appid.
Now open Component Services, Computer, My computer, DCOM config and find ( from the Registry keys above) the Description, it should be Runtime Broker, at least it was for me, if it's other then do it for the exact Component service, right click then Properties then Security tab, then open the Launch and Activation permissions Edit button and depending on the Event Viewer description if it's Local Service or System, click Add, add one of the two and enable the box " Local Activation".
Now go back to regedit and for the CLSID & Appid changed ownerships revert back to default TrustedInstaller.
(You should write NT SERVICE\TrustedInstaller to revert ownership to default).Reboot and Error 10016 is gone forever.

I tried to use this method, my issue is a system error ( event ID 10016) :

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {C2F03A33-21F5-47FA-B4BB-156362A2F239} and APPID {316CDED5-E4AE-4B15-9113-7055D84DCC97} to the user michele\my pc SID (S-1-5-21-2832376193-1952021688-2811500842-1001) from address LocalHost (Using LRPC) running in the application container Microsoft.SkypeApp_12.8.487.0_x64__kzf8qxf38zg5c SID (S-1-15-2-2246530975-808720366-1776470054-230329187-4153223113-3550430174-4193313734). This security permission can be modified using the Component Services administrative tool.

You can try adding launch and activation permissions for user "All Application Packages" and see if that helps. I assume you have already added those permissions for the user "my pc"; if not, do that first. Finally, even after having added all the right permissions you may still see these error messages. Microsoft badly broke their DCom system in Windows 10, so some of these errors cannot be resolved. Word on the street is that you can ignore these errors safely, but nobody knows for sure.

Why? Why would you want to give all apps that authority? To do what?

Sure it would remove the error message but at the expense of giving every single Windows Store app the authority to do whatever they want. Authority for Store Apps is complex and a "whatever, do what you want" approach is rather cavalier I think.

Or you can randomly give authority to processes to do what they want and swap an increased risk for less messages.

Only you can decide if randomly changing permissions is better than living with incorrectly written messages to a log you would only look at if you had a problem.

I agree with your point though on the whole.

So people without any knowledge about registry&co should just ignore this error yes?

is the last step important?
"Now go back to regedit and for the CLSID & Appid changed ownerships revert back to default TrustedInstaller."
because ive found a more detailed guide to your way of fixing this but theres no mention of it..

Thanks
